. 2 Claims. (01. 106-277 V. 1 2 This invention relates to a composition for EXAMPLEII printing color on asbestos-cement products and the like, such as sidings and shingles. y, API 9. In my copending application Serial No. 216,870, Viscosity, F., Saybolt Univ 60-65 now abandoned, I have disclosed an asbestos-0e; 5 ASTM max merit product having a surface orimon P0111, degree F race by indenting the surface of a freshly formed Flashi sheet of the material accordin to a predeter- Min mined design or pattern and simultaneously printe 6 F'- ing or applying coloring matter in the indentations. While it is preferred to apply the color EXAMPLE m to the indentations or vales, it may be applied to Gravity API 36 0 the ridges, or even upon a flat surface. Flash degree 6 The present application is a continuation-in- Fire hegree F 345 mm part of said application Serial No. 216,870 and re- 15 1.

Among the obiects of the invention are to pro- 0 Viscosity, F" saybolt 352 vide a coloring composition that will not smear, blend, drift, or bleed when applied to a freshly formed sheet of asbestos-cement so as not to distort the applied design.

A further object is to provide a composition that will not inhibit hydration of the cement, or deleteriously effect any of the properties of the finished product.

The colorin osition broadly described, comprises a dry "coloring pggder mix composed oF'igmen and m Pgrtland cement,

In preparing a preferred form of vehicle, about 10 parts by weight of oil or hydro'afbdi'i of the a on parts 0 Example I weight, of a suitable bod in a ent for 7 liquid hydrocarbons such as the multi' ie E aroxy aluminum soa s of na hthenic, oleic, cocoanut acids, and the like. The mixture is heated to about 140-150 F. while being gently agitated. The mixture is continued at that temperature, under agitation until it is uniform, clear, and free either prior o application of the Composition of any undissolved matter, after which it is perafter the coloring matter has been deposited, and that will not effect the cement so as to inhibit its ultimate hydration after the vehicle has been released by evaporation, or by absorption into the asbestos-cement base.

The following are examples of oils or liguid hydrocarbons, that I have found 0 ave suitable characteristics for use as the vehicle, oils of such character may e used either a one or in combination; Other oils or hydrocarbons of similar EXAMPLEI we a; 1 Specific gravity at F 0.7750.825 Flash point, Pensky-Martins (closed cup) F. min.

mitted to cool.

The dry ingredients consist of hydraulic ce 40 oxide, chrome oxide reen, black xide, etc. The

ry ingre 1cm 5 are ground together in a ball-mill or other suitable apparatus, and the powdered dry ingredients are then gradually added to the vehicle while the mixture is being agitated.

The following are typical examples of the composition for different colors:

Green N Glormal Portland cement parts by weight" 82 Chrome oxide green do- 14 Titanium dioxide do 4 100 Vehicle parts 35 Caluminum cement (Lumnite) parts by weight 89 Black oxide do 9 Titanium dioxide do 2 100 Vehicle parts. 26

4. Brown Gray hydraulic cement parts by weight 90 Brown oxide do 10 100 Vehicle parts.... 44

It is to be understood that the foregoing formulas are given by way of illustration, and are subject to variation. It is desirable to keep the vehicle content to the minimum consistent with good results because if the oil or liquid hydrocarbon content is too high smearing of the color may result in handling the freshly made printed blanks. The amount of oil vehicle required to obtain a composition of satisfactory viscosity will vary somewhat with the amount of oxide pigments used in the mixture.

What I claim is:

1. A composition of printing consistency for application to a freshly made base of Portland cement reenforced with asbestos fibers, consisting of powdered Portland cement and pigment, in a vehicle. consisting of a liquid hydrocarbon that will not inhibit hydration of the cement of the base, and an aluminum soap.

2. A composition of printing consistency for application to a freshly made base of Portland cement reenforced with asbestos fibers, consisting of powdered Portland cement and pigment, in .a. vehicle consisting of a liquid hydrocarbon that will. not inhibit hydration of the cement of the base, and a bodying agent consisting of at least one of the hydroxy' aluminum soaps selected from the group consisting of naphthenic, oleic, and cocoanut acids.
